Question 1 Is the expression x^3*x^3*x^3equivalent to x^(3*3*3)? Why or why not? Explain your reasoning. No because the law of exponents Question 2 Rewrite in simplest radical form 1/x^((-3)/6) Show each step of your process. Question 3 Rewrite in simplest rational exponent form √x • 4√x. Show each step of your process. Question 4 Rewrite in simplest radical form x^(5/6)/x^(1/6) Show each step of your process. Question 5 Which of the following expressions are equivalent? Justify your reasoning. 4√x3 1/x^(-1) 10√x5•x4•x2 x^(1/3)*x^(1/3)*x^(1/3)

|dw:1442874176073:dw| Look at that exponent in the denominator and note that it is: A. fraction (that can be reduced......and B. it is negative. what do you want to do first? reduce the fraction or take care of the negative......both will have to be accomplished regardless.
anonymous
  • anonymous
so its exponent is -1/3?
radar
  • radar
You reduced it but you made an arithmetic error......3/6 reduces by dividing top and bottom by same number......try 3..

OH! -1/2
radar

Yes. now we have this:|dw:1442874636974:dw|. When a variable like x has a negative exponent and it appears in the denominator of a fraction where do you have to move it to make it become a positive exponent?

idk do u make is one over the sqr root of x?
radar
  • radar
What if you multiplied top and bottom (numerator and denominator by x^(1/2) giving you this:|dw:1442875018974:dw|
radar
  • radar
Or a simple rule if you move it across the line, the sign of the exponent changes.

Number three is pretty straight forward, give it a try. I will be back.
anonymous
  • anonymous
ok thnx so much for that
radar
  • radar
Number 4 is a division all you have to do is subtract exponents for division. and Number 5, simplify the second and last one and see what you come up with.

oh ok thank u so much. this helped

Good luck with your studies. Exponent rules become more understanable with practice.
